Package: fftw-docs
Version: 2.1.3-22
Severity: normal
I ran "make" in the "tests" directory to generate the testing programs.
(Note that the executables are names "test_fftw" and not "fftw_test" as
the documentation says; this should be changed to make things agree.)
test_fftw -v -p 0 passed the planning test; but everything else failed.
test_fftw -v -a 0 gave FATAL ERROR: test_out_of_place: wrong answer
(with "howmany = 2")
test_fftw -v -c 1x1 failed with a segmentation fault
test_fftw -v -r 0 failed with "NaN in answer" for n = 1144, dir = forward
test_fftw -v -r 1 failed with "NaN in answer" for N = 4032
test_fftw -v -s 1 says that glibc's malloc() gave memory corruption
This is an AMD Athlon machine. Apparently the fftw libraries optimized
for the k7 architecture are no longer available (again, in disagreement
with the documentation the recommends them.)
Despite these test failures, a program I compiled a few years ago that
uses the fftw libraries seems to work OK. Maybe this has to do with the
newer compiler in use, which is now gcc-4.3?
Here's what I have (output from "aptitude search fftw"):
